我们考虑与李代数相关的XXX型和Gaudin量子可积模型。模型定义在不可约模的张量积上.对于每个模型,存在N个单参数交换算子族,称为传递矩阵。我们表明,这些模型的Bethe向量,给出的代数嵌套Bethe变换,是高转移矩阵的特征向量,并计算相应的特征值。
We consider the XXX-type and Gaudin quantum integrable models associated with the Lie algebra . The models are defined on a tensor product of irreducible -modules. For each model, there exist N one-parameter families of commuting operators on , called the transfer matrices. We show that the Bethe vectors for these models, given by the algebraic nested Bethe ansatz, are eigenvectors of higher transfer matrices and compute the corresponding eigenvalues.
